Background: One of the candidate landing sites for the Mars Science Laboratory is in the Mawrth region of Mars. The candidate landing ellipse is located on highly cratered terrain with extensive bedrock outcrop. Diverse hydrous minerals have been detected from orbit, providing strong motivation for sending a landed mission to this area. However, models for the accumulation of bedrock in the are...

Recent numerical simulation of tsunami propagation proposed a new hypothesis about the origin of the 1771 tsunami that devastated the southwest Ryukyu district of Japan; a slip of the East Ishigaki Fault, a 44kmlong fault lying 50km off the east coast of Ishigaki Island, might be the cause of the 1771 tsunami. The present study is to test this hypothesis through visual observation by means of t...

Thermodynamic calculations for selected silicate-oxide-fluorite assemblages indicate that several commonly occurring fluorite-bearing assemblages are restricted to relatively narrow fo,-fF> fields at constant P-T. The presence of fayalite-ferrohedenbergite-fluorite-quartz *magnetite and ferrosalite-fluorite-quartz-magnetite assemblages in orthogneisses from Au Sable Forks, Wanakena and Lake Ple...

Introduction: The APXS (Alpha-Particle X-Ray Spectrometer) onboard the Mars Exploration Rovers (MER) has returned element abundances of over 200 soil and rock samples at both the Opportunity and Spirit landing sites [1]. Besides major elements, a selection of trace element concentrations including Ni, Cr, and Zn are also available. These data demonstrate that the trace element abundances of Mer...

Recently, ground-based hyperspectral imaging has come to the fore, supporting the arduous task of mapping near-vertical, difficult-to-access geological outcrops. The application of outcrop sensing within a range of one to several hundred metres, including geometric corrections and integration with accurate terrestrial laser scanning models, is already developing rapidly. However, there are few ...

Observations of slab-a\'alanche releases in alpine terrain ha\'e led to the hypothesis that rocky outcrops can influence thc spatial distributions of temperature and heat flow in dry alpine snow covers and thus c011lrol the local distribution of de pth hoar. \ Vc investigate the effects of terrain on crystal growth by using a two-dimensional finite­ element model of heat flow coupled with a mod...
